I did try that too. 'slapcat' took 6 minutes, and 'slapadd' to an empty
directory wanted 15hours. If I move the ldif file to the x4500 where I have 16GB
of /tmp, I can 'slapadd' it all in 13 minutes, then rsync the data back to the
master and disk (3 minutes).

I just thought the whole rsyncing the binary db files to be 'uglier' than having
2.4 syncrepl against a 2.3 until it was up to date.
